Post-cycling Interface Strength Test of Geogrids
(2020-07-01)
Geosynthetic-reinforced soil structures are commonly used in seismic design in regions. The performance of GRES under seismic conditions can be found to range from very good to catastrophic. This paper presents the ...
Fatigue behavior of bainitic and martensitic super clean Cr–Si high strength steels.
(Oxford, 2014-04)
This study compares the fatigue behavior of quenched/tempered and austempered super clean Cr–Si high strength steels (HSS). The microstructure of the quenched and tempered steel consisted of tempered martensite and that ...
Estimating common sectoral cycles
(Elsevier Science Bv, 1995-02)
We investigate in this paper the degree of short-run and long-run comovement in U.S. sectoral output data by estimating sectoral trends and cycles. A theoretical model based on Long and Plosser (1983) is used to derive a ...
A model for fatigue crack propagation during high cycle fatigue
(Carl Hanser Verlag, 2017-01)
This paper deals with the prediction of high-cycle fatigue behaviour for four different materials (a 7075-T6 alloy, a Ti-6Al-4V alloy, JIS S10C steel and a 0.4%C steel) using Chapetti´s approach to estimate the fatigue-crack ...
Estimation of the plain high-cycle fatigue propagation resistance in steels
(Universidade Federal de São Carlos, 2002-12)
In this work a method to estimate the high cyclic fatigue propagation life of steel specimens under constant loading is presented. This method is based in experimental evidence that the fatigue limit represents the threshold ...
A bumpy ride: structural inequalities, quality standards, and institutional limitations affecting cycling infrastructure
(Elsevier Ltd, 2022)
Structural socio-economic and institutional limitations can affect the implementation of cycling infrastructure. More stringent cycling infrastructure standards aiming to solve deficiencies might exacerbate disparities, ...
Bridgeless interleaved boost PFC converter with variable duty cycle control
(2011-12-28)
This paper proposes a bridgeless boost interleaved PFC (power factor correction) converter with variable duty cycle control. The application of bridgeless technique causes reduction of conduction losses, while the interleaving ...

(2011-12-28)
This paper proposes a bridgeless boost interleaved PFC (power factor correction) converter with variable duty cycle control. The application of bridgeless technique causes reduction of conduction losses, while the interleaving ...
Are the Mexican States and the United States Business Cycles Synchronized?. Evidence from the Manufacturing Production
